l clear, and exact description.

The invention relates to saw mills, and its object is to provide a new and improved recorder, forming a permanent feature of a saw mill, and arranged to form a ermanent record of the amount of boar measure contained in the logs sawed by the saw mill.

Theinvention consists of novelfeatures and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding partsin all the views.v

Figure l is a side elevation of the improvement as applied to the saw mill carriage supporting a log to be sawed; Fig. 2 is an enlarged transverse section of the improvement; Fig. 3 is a similar view of the same on the line 3 3 of Fig. 1; Fig. 4 is an enlarged sectional elevation of the improvement on the linel 4 4 of Fig. 2; Fig. 5 is a plan view of the same, the casing being shown in section; Fig. 6 is an end view of the printing cylinder and the means for adjusting and locking the same; Fig."7 is a longitudinal sectional elevation of the printing cylinder, the inking ribbon and the strips of paper on which the impressions are made; and Fig. 8 is a perspectiveview of one of the paper roll holders.

The recorder is mounted ori a suitable framework A, attached to one end ofthe saw mill carriage B of a saw mill of any approved construction, the said carriage being provided with a head block C, capable of transverse movement on the carriage, and adapted to be set according to the diameter of a log D, to be cut into boards or other lumber by thev saw of the saw mill.

In thecasing E of the recorder is arranged a printin cylinder F, normally turning with its shaft by the action of a spring F, coiled on the shaft F and secured with one end to nected by a bevel gear wheelV G with a bevel lgear wheel GQ secured on `the upper end ofa shaft G2, journaled in suitable bearings arranged on the framework A and the casing E, andon the lower end of the said shaft G2 is secured a bevel gear Wheel G3 in mesh with a bevel'gear wheel G4, attached to a longitudinally extending shaft G5, journaled in suitable bearings arranged on the saw mill carriage B. On the shaft G5 is secured a gear wheel G6 in mesh with a rack C secured to or formin part of the head block G, so that when t e latter is shifted transversely on the saw mill carriage B then the rack C rotates the gear wheel G, whereby the shaft G5 is turned. The rotary motion of the shaft G5 is transmitted by the gear wheels G4, G3 to the shaft G2, and the rotary motion of the latter is transmitted by the gear wheels G, G to the shaft F to rotate the printing cylin- 'der F, it being understood that the cylinder F is normally carried along by the action of the spring F2.

By the arrangement described, the printing cylinder F is turned correspondingly to the distance the head block C is moved on the carriage B, that is, the printing cylinder F is turned correspondingly to the diameter of the log D held on the saw mill carriage B.

On the printing cylinder F are peripherally arranged sets, of type H, representing board measure for dierent lengths of logs. For instance, the left hand set of type represents board measure for logs twelve feet long and of any diameter, while the next set of type indicates board measure for fourteen feet logs of any diameter, and so on. It is'un# -derstood that I do not limit myself to the particular sets of types shown, as in practice the recorder embraces such length of logs as are usually cut by a saw mill, and logs of diameters running, say, from eight to forty or more inches in diameter.

Over the t pe of the printing cylinder F eX- tends, lengt wise thereof, an inking ribbon I, unwindlng from a ribbon holder I and winding up on a roller I2, both rollers I and I2 being journaled -in suitable bearings arranged in the casing E. The inking ribbon I thus extends over the type ofthe several sets of type at the top of the cylinder F at the time, and above the inking ribbon I and in transverse alinement with the several sets of type H, are arranged strips of paper J, each unwinding from a roll of paper J',

' journaled on a suitable bracket E', a. ranged in the casing E at the rear side thereof. The forward end of each strip of paper passes between feed rollers K and li journaled in brackets E3, arranged in the casing E. N ow in order to make an impression, a platen L is provided for each set of type H, each platen L being held on alever L `iournaled on a bracket E4, arranged in the casing E, and the lever L is pivotally connected by an adjustable link L2 with a key N, fulcruined at N at the rear side of the casing E, the forward end of the key N extending through a slot in the front of the casing E. The outer ends of the several keys N are provided with finger-pieces N2, bearing numerals corresponding to the length of the logs to be sawed by the saw mill C, the said numerals bearing a corresponding relation to the numerals of the type H representing board measure for different diameters of logs in inches and the corresponding length of the logs in feet. New when the head block C is set for a log D of say twenty-four inches in diameter, then the cylinder F is turned correspondingly, so that the types H for the board measure of twenty-four-incli diameter lo 's appear at the top of the cylinder, vand w ien the operator vnow presses the finger-piece IN2 bearing the numeral for the length of the log D on the saw mill carriage B at the time, then the cor-` responding platen L is swung downward, to cause an impression to be made on the strip of paper J, the impression corresponding to the numeral of the type H, and indicating the full board measure of the log D on the carriage B at the time. Thus if the log D is twelve feet long, the finger-piece N2 to the extreme left will be pressed by the operator, but if the log is eighteen feet long then the-middle finger-piece will be pressed, and if the logl is twenty-four feet long the fingerpiece N2 at tlie extreme right will be pressed by the operator. Now if the log D is say twelve feet long and twenty inches in diameter, then the numeral 192 will be printed on the strip of paper J by the corresponding type of the iirst set of type H'on the lefthand side of the printing cylinder F, the said numeral 192 indicating the feet board measure of the log. It -is understood that in this case the key N bearing the numeral 12 is pressed at the time the head block C is set to twenty inches. lf a log D is twenty-four feet long and say twenty-four inches in diameter, then the numeral 600 (that is, the feet board measure for such size log) is printed on the strip of paper J for the key N marked 24, and in this manner the -board Ineasure for the logs sawed by the saw mill is recorded and a permanent record made thereof on the several strips of paper J.

From the foregoing it will be seen that the printin cylinder F is turned a distance correspon ing to the diameter of the lo to be Sawed at the time and in place on t e saw mill carriage B, and the impression is made by the corresponding key N according to the length of the log.

The strip of paper J rinted on at the time of pressing a key N, is Ved forward on the release of the key, the latter being returned to its normal position by a spring O. Now for the purpose' mentioned, each key N is provided with an u wardly extending arni P, carrying a pawl engaging a ratchet wheel P2, secured to and forminflr part of the corres onding feed roller K. New when the key lis pressed, the pawl F glides over the teeth of the ratchet wheel P2, and when the key N is released and swings upward by the action of its spring O, then the pawl P turns the ratchet wheel P2 and consequently the corresponding feed roller K, to feed the strip of paper J forward, to bring a blank piece of Iper over the type on top of the printing inder F at the time.

ln order to adjust and lock the printing cylinder F in place during the time an inipression is to be made on pressing the corre.- sponding key N, the following arrangement is made: On one end of the printing cylinder F is secured a toothed wheel Q, adapted to be engaged by the angular end Q of,y an arin Q2, secured on a lever R, fulerumed at lt at the rear side of the casing E, the forward end of the lever R being provided with a longitudinally extending bar R2, extending under the several keys N, so that when one of the keys is pressed, as previously explained, then a downward swinging motion is given to the lever R, to move the angular end Q of the arm Q2 into engagement with the adjacent teeth of the toothed wheel Q. l/Vhen this takes lace, the toothed wheel and consequent y tlie printinfr cylinder F are locked against rotation. 'lhe teeth of the toothed wheel Q are referably pointed, as plainly indicated in igs. 2 and 6, so that when the diameter of a log D is a fraction more than a whole number, then the printing cylinder F is turned a corresponding distance, and when a key N is now pressed and the lever R swings downward, then vthe angular arni Q engages the corresponding side of the pointed en of the tooth of the wheel Q, to turn the printing cylinder F either forward or backward, until the angular arm Q passes accuratel between adjacent teeth of the wheel Q. hus, if the fraction is less than one-half, the cylinder F is turned backward, but if it 'is more than one-half, it is turned a'corresponding distance forward, to insure correct rplcolrding of the amount of board measure in t e o Theglever R is normally held in an upermost osition b the action of a s ring 2 (see ig. 2), andY on the said lever 't are secured u wardly extending sprin awls I2 I4 adapte 'to en age ratchet wheel .5, I secured to the rib on rollers I and I2. The

-u'p to give thc total.

pawls I3, I4 are adapted to be engaged by the lug Q has passed between a pair of teeth arms I7, I held on a shifting bar I", mount-ed to slide longitudinally inthe casing E and provided at one end with a handle I, 'adapt'- ed to betaken hold of by the operator to shift the. bar I either to the right or left, to move one of the pawls I3, I4 out of mesh with thc corresponding ratchet wheel I5 or I", whilethe other pawl I4 or I3 moves in mesh with the. corresponding ratchet I or I5. N ow when the lever R is on the return or upward stroke, the pawl Ia or Ii in mesh at the time with the corresponding ratchet wheel I5 or I, turns the latter and the corresponding ribbon roller I or I2, to shiftthe ribbon I longitudinally. Thus, by the arrangement described, clear impressions are always had on the strips of paper J.

ln order to' support the strips of paper J in )roper )osition over the in ing 'ribbon I, longitudinally su )porting bars S and S are provided, located on opposite sides of the mking ribbon I, for h'oli ing the paper above the latter, as will be readily understood by reference to Figs. 2 and 5.- 'I he upward swinging motion of the levers L carrying the platen li is limited by stops E5, arranged on the bracket EL Each strip of paper J after it leaves the rollers li, li winds on a roller K3, journaled on a suitable bracket Ei arranged in the casing E, and the roller li is connected by a pinion lit, with a gear wheel K5 ressed on byA a coil sprmg li, to drivev the ro ler la with a` view to wind up 'the strip of paper on the said roller li. By providing a single strip ol paper J` for each set of ty pc II on the printing cylinder F, each strip of )aper receives thereon in succession and witlhout large intervening spaces, the numerals ofthe logs o f the same length for each strip, and hence the numerals on each strip can be readily added It will also be seen that a new strip of paper J may be readily inserted in case one 1s used up, and hence it is not` necessary to disturb the other strips of paper not vet used' u 'lhe printingI cylim er F is free to rotate independently of the. impression devices, and the printing cylinder rotates forward and l ack\\'ard on moving the' head block C transversely in a` corresponding direction, but thc properke)v N is not pressed until the head block and the printing cylinder are at rest, that is, at the time the head stock has been set to the exact diameter of the log to be sawed, and the corresponding longitudinal row of types Il is on the top of the printing cylinder l". i

In case the diameter of the log is a fraction of an inch over or under a certain number of inches and the key N is pressed, then the printing cylinder F is slightlyturned forward or backward on its now stationary shaft F and against the tension of the spring F2, until on the wheel Q as previousl explained. When the key is released an the lug -Q moves out of engagement with the teeth, then the printing cylinder F returns to yits -normal position on the shaft F bythe action of the spring F2. Y

Although I have described the several mechanisms in detail, it is evident that other mechanisms for accomplishing the same or a vsimilar result may be used, and hence I do not limit myself to the detail mechanisms shown and described, as the same may be varied without deviating from my invention.
